STEAM-ACTUATED VALVE.

SPECIFICATION forming part of Letters Patent No. 552,081, dated December24, 1895.

Application filed March 20, 1895. Serial No. 542,463. (No model.)

To all whom it may concern.- 15. Extending from the steam-chamber Be itknown that I, GEORGE H. WILLIAMS, through the steam-chest to thecylinder are of Marion, county of Grant, and State of Inthe steam-ports16, and extending from the diana, have invented a certain new andusecylinder are the exhaust-ports 1'7, which are 5 ful Steam-ActuatedValve; and I do hereby first vertical andthen horizontal, as seen indeclare that the following is a full, clear, and Fig. 6, leading out at18. exact description thereof, reference being had Between thesteam-chamber 15 and the va to the accompanying drawings, in which likerious valves 9, 11 and 12 and the cylinder are numerals refer to likeparts. a number of passage-ways for the passage of 10 My inventionrelates to a steam-actuated steam, whereby it is enabled to actuate suchvalve which in construction is wholly indevalves sem'ate'm and preventcentering. These pendent of the piston andis so arranged that itpassage-ways in one end of the steam chest will admit steam to thecylinder and exhaust it and cylinder are the same as those in the otherand avoid centering the piston. I use a series end thereof and they areall made straight, 6 5 t 5 of piston-valves so provided with passage inorder that the device may be economically ways from each other and thesteam chamconstructed. By placing the steam-chest in her and cylinderthat they and the piston will a drill-press and by using jigs it is seenthat coact successively on each other and thus although the number ofpassage-ways may prevent the centering of the piston. The conseem greatthey may be very quickly made. 70, 2o struction is such also that it isvery economi- To register with these passage-ways, as well cal and ofsmall dimensions. I have used it as the steam and exhaust ports, thevalve 9 in connection withasteam-pump;butit can be is provided with theannular grooves 19, the used with any other steam-engine. The full valve11 with the annular grooves 20 and the nature of its construction andmode of opervalve 12 with the grooves 21. The arrange- 2 5 ation will beunderstood from the accompanyment of these passage-ways and theoperation ing drawings and the description following. of the device willbe understood from the fol- Figure 1 is a plan view of the steam-chestlowing explanation: Suppose the piston is at with the cover and gasketremoved.

Fig. 8 12, anddrives it to the position shownin Fig. 3. 35 is a bottom view of thesteam-chest. Figs. 9 Then the annular groove 21 in the valve 12 and 10are the same as Figs. 2 and 3, excepting opens the passage-way 23,allowing the steam that they show the position of the valves to enterfrom the steam-chamber 15 through when the piston is at the opposite endof its the passage-ways 24, 25 and 26 into the end I stroke. of the mainvalvechamber 10, whereby it 40 I show here an ordinary cylinder 1 andpisdrives the main valve 9 to the position shown ton 2. On the cylinderis mounted a steamin Fig. 2, at the same time such auxiliary valve chest3 havinga cover 4, to which is connected 12 opening the passage-way atthe other end asteam-pipe 5. Betweenthe cover and steamof thesteam-chest to exhaust the other end chest is a metal gasket 6. Theparts are conof the valve-chamber 10. WVhen the valve 9 45 nected in theusual way by bolts 7 through is moved to the position shown in Fig. 2,the holes 8. Within the steam-chest I provide a annular groove in oneend registers with the main piston-valve 9 moving in itsvalve-chamsteam-port 16 and at the other end with the her 10, and alsotwo smaller auxiliary pistonexhaust-port 17, allowing the steam to befed valves 11 and 12 moving in the valve-chamto the cylinder directlyand exhausted there- :00 5o bers 13 and 14, respectively. Above thefrom.

valves and the gasket 6 is a steam-chamber So far the auxiliary valve 11has not been acted upon; but as soon as steam is introduced to drive thepiston back from the position it occupies in Fig. 2 steam passes throughthe passage-way 27, as shown in Fig. 3, that leads into the end of thevalve-chamber 13 behind the valve 11, whereby it is driven into theposition shown in Fig. 9, and the annular groove in the valve 11registers with the passageway 28, through which steam is exhausted fromthe end of the valve-chamber 14, as shown in Figs. 3, 4 and 8, allowingthe valve 12 to be moved back. At the same time it opens the passage-way22 at the other end of the steam-chest, allowing the steam to enter theother end of the valve-chamber 14 behind the valve 12. From this pointon the process which has heretofore been described is repeated as thepiston moves backward and forward.

To recapitulate the passage-ways for conducting live steam: There is apassage-way from the cylinder to the end of the chamber 14 that passesthrough the auxiliary valve 11, a second passage-way between thesteamchamber 15 and the main valve-chamber 11 going through theauxiliary valve 12. There is the main steam-port from the steam-chamber15 through the main valve to the cylinder, and, fourth, a passage-wayfrom the cylinder to the end of the valve-chamber 13.

The following passageways and ports exhaust the steam: First, there isan exhaust passage-way 28 from the end of the chamber 14 that goesthrough the valve 11. In the sec 0nd place, there is an exhaustpassage-Way from the main valve-chamber 10 through the passage-ways 26,25, 30 and 31 and going through the valve 12. Third, there is a mainexhaust-port 17 from the cylinder that goes through the main valve 9. Inthe fourth place, there is the exhaust passage-way 27 from the end ofthe chamber 13 into the cylinder. This valve mechanism may be entirelyindependent of the cylinder and I have used it in that What I claim asmy invention, and desire to secure by Letters Patent, is

1. The combination with a steam cylinder and piston, of a steam actuatedvalve mechanism comprising a steam chest provided with chambers orsecondary cylinders extending parallel with the main cylinder andpassage ways connecting the chambers or cylinders and steam inlet, andthe piston valves 9, 1.1 and 12 fitting in said chambers so as to slidetherein and shut off or open up the passage ways, the passage ways andvalves being arranged in such order that the steam will act upon them insuccession, substantially as set forth.

2. The combination with a steam cylinder and piston of a valve mechanismcomprising a main piston valve and two auxiliary valves, a steam chestprovided with a steam passage way leading from the cylinder through thevalve 11 into the valve chamber 14, another from the steam cha1nber'15through the valve 12 into the main valve chamber 10, another from thesteam chamber 15 through the main valve 9 into the cylinder and anotherfrom the cylinder into the valve chamber 13, and an exhaust passage wayfrom the valve chamber 14 through the valve 11 into the exhaust port 17,another from the main valve chamber 10 through the valve 12 into thesteam port 17, another, the main exhaust port, from the cylinder throughthe main valve 9 and another from the valve chamber 13 into thecylinder, substantially as shown and described.

In witness whereof I have hereunto set my hand this 2d day of March,1895.
